HOLDER FOR ROTARY RINGS.

Specification of Letters Patent.

Application filed June 15, 1908.

.Patented Mar. 22, 1910.

Serial No. 438,517.

To all whom it may concern:

Be it known that I, BIOKNELL HALL, of Taunton, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Holders for Rotary Rings, of which the following is a specification.

This invention has relation to rotary spinning rings and has for its object to provide certain improvements in the holders or bearings therefor for simplifying their construction, for preventing the accumulation of dust and lint, and for making it easier to insert and remove a spinning ring.

On the accompanying drawings, Figure 1 represents in plan view, a ring and holder embodying the invention. Fig. 2 represents a section on line 2-2 of Fig. 1. Fig. 8 represents a plan view of the ring holder. Fig.

- 4 represents a section on line tt of Fig. 1.

Fig. 5 shows another form of post for limiting the lateral and axial movement of the ring. Fig. 6 shows another form of ring with a difi'erently shaped post.

Referring to the drawings, a spinning ring is indicated at a, and it is illustrated as provided with the usual traveler race a to receive the traveler a. The inner wall of the ring tapers inwardly and downwardly from the race, as indicated at a so as to provide an annular internal projection.

The holder comprises a base which is preferably in the form of an annulus as indicated at b, a plurality of upwardly projecting posts 6 upon which the bottom of the ring may rest, and a plurality of separate posts 5 which limit the upward or axial movement of the ring, and which also limit its transverse or lateral movement. The holder may be conveniently stamped out of a thin sheet of metal, and the ringsupporting posts 6 may be formed by bending upward tongues cut on the inner wall of the ring or annulus. The posts 6 likewise consist of tongues which are formed on the inner wall of the ring or annulus b and bent upwardly as shown in Figs. 2 and 4. Instead of being arranged exteriorly to the ring at, these last-mentioned posts are arranged interiorly and they extend into the ring so as to form, as it were, an internal hearing. The said posts 6 are preferably divergent so that their ends flare outwardly to approximately conform to the beveled or converging inner face of the ring a. Preferably, the ring a fits so loosely around the posts 6 that it is capable of a limited lateral and axial movement whereby it may yield to the unbalanced strains of the yarn. The outer surfaces of the posts 6 are convex as are the upper ends of the posts 7). The looseness with which the ring fits the holder enables the ring to rise more or less from the posts 6 so as to allow lint or dust to be dislodged or removed in the event that it collects at the edges of any one of the posts. One or all of the posts 6 are sufficiently resilient so that the ring may be removed by pulling upon it axially, and it may, by moving it in the opposite direction, be snapped'into place.

Of course it will be understood that the precise details of construction of the holder which I have described, are not essential to the invention, since the posts 5 and b may be formed separately and secured to the base 6. Their shape may be varied as desired. In Fig. 5, for instance, the posts 5 have out-turned ends 6 to engage the internal wall of the ring, and in Fig. 6, the ring has the flange a which may be engaged by the bent end o of the post 6 Though I have illustrated four posts Z) and four posts 6 it is apparent that I may use a greater or smaller number of each.

The chief purpose of mounting the ring a in the manner described is to enable it to revolve freely and to be entirely free from any accumulation of lint. The rapidly rotating bobbin extending through the ring sets up what might be roughly termed a vortex or rotating air current within the ring, the force of the vortex being increased by the yarn upon the bobbin because of the fibrous nature of the rough surface of the yarn. The effect of this vortex is shown by the particles of lint which are blown out of the ring as if by centrifugal force. The fact that the individual supporting and retaining tongues are separated by wide spaces enables the vortex or air current to enter between ring a and each of the tongues by which it is engaged. If, instead of the retaining tongues .79 a continuous or substantially continuous retaining ring were provided for engaging the interior surface of the spinning ring a, the vortex would be prevented from entering between the cooperative surface of the spinning ring and retaining ring because the retamlng ring would in that event constitute a barrier between the vortex and the spinning ring.

It has been demonstrated in practice that a ring mounted upon a supporting base formed in accordance with this invention rotates at a very much slower speed than the bobbin, so that, although the spinning ring is rotating with relation to its supporting base, its speed is so slow with relation to its bobbin that it receives substantially the full force of the vortex. The force of the vortex is such as to not merely remove particles of lint from the cooperative surface of the spinning ring and the several tongues, but it is such as largely to prevent such particles from becoming lodged in the first instance.

Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the modes of its use, I declare that what I claim is 1. The combination with a rotary spinning ring having a traveler race, of a holder or bearing therefor comprising a base and posts rising therefrom and projecting loosely into the interior of said ring so as to permit said ring to rotate.

2. The combination with a rotary spin ning ring having a traveler race of a holder or hearing therefor, comprising a base having means for supporting said ring and separate members extending loosely into the interior of said ring for holding said ring against undue lateral movement, while permitting it to rotate.

3. The combination with a rotary spinning ring having a traveler race and an internal annular projection at its lower end, of a holder or bearing therefor comprising a base having means extending into the interior of said ring and coacting with said annular projection for holding said ring against undue axial and lateral movement, while permitting it to rotate, said base also having means for supporting said ring.

4. A holder for a rotary spinning ring comprising a flat base, and a plurality of independent posts integral therewith constructed and arranged to loosely engage the interior wall of said spinning ring to permit the rotation of said ring.

5. A holder for a rotary spinning ring comprising a base, a plurality of posts upon which the ring may rest, and a plurality of posts constructed and arranged to eX tend into and engage the interior surface of the ring to limit its movement.

6. A holder for a rotary spinning ring, comprising a base, and a plurality of diverging posts extending from said base so as to project into and engage the inner surface of the ring.

7. A holder for a rotary spinning ring comprising a base, a plurality of posts for supporting the ring, and a plurality of posts to project into and engage the interior surface of the ring, one or more of said lastmentioned posts being resilient.

8. A holder for a rotary spinning ring comprising a base, and resilient means adapted to project loosely into the ring to yieldingly retain the ring on the holder and permit it to be sprung into and out of place on said holder, and to permit the rotation of the ring.

9. The combination with a rotary spinning ring having a traveler race and an inwardly and downwardly tapering interior wall, of a holder comprising a base and a plurality of posts constructed and arranged to engage said tapering wall so as to permit the rotation of said ring substantially as set forth.

10. A sheet metal holder for a rotary spinning ring consisting of a substantially flat apertured base, having tongues at the edge of the aperture bent upwardly and outwardly diverging so as to extend into the interior of the ring, and also having means on which said ring may rest.

11. A sheet metal holder for a rotary spinning ring consisting of a substantially flat apert-ured base, having tongues at the edge of the aperture bent upwardly and outwardly diverging so as to extend into the interior of the ring, and also having faces 01' surfaces between some of said tongues to support said ring.

In testimony whereof I have afiixed my signature, in presence of two witnesses.

BICKNELL HALL.
